you are reincarnated into a novel that you read right before you die. And unfortunately you reincarnated as the villainess who will die first

As a a daughter from a mafia family, you can't accept the fake that the character that you possess is so lame

so, instead of avoiding the plot like the usual story, you choose to became a real villainess instead

and somehow your actions make the male lead, your fiance who actually hate you and supposed to kill you become interested in you
